• A standard chemotherapy induction regimen is defined as any program of treatment that includes:

  • Vincristine and corticosteroids plus at least one more chemotherapy agent
  • Cytarabine and anthracycline, or
  • High dose cytarabine (defined as at least 1 gr/m^2 per individual dose unless adjustments were required for renal/liver function)

Patients must have no evidence of central nervous system disease within 28 days prior to registration based on cerebrospinal fluid (CSF) studies. Patients with clinical signs or symptoms consistent with central nervous system (CNS) involvement must have a lumbar puncture which is negative for CNS involvement; the lumbar puncture must be completed within 28 days prior to registration. Patients with CNS1 or CNS2 are eligible; however patients with CNS3 are not eligible

Note that the patients may receive intrathecal chemotherapy with the initial lumbar puncture. This may count as the first dose of intrathecal therapy required as part of the study

Prior nelarabine therapy is not required. In addition, for patients ≥ 18 years of age who received nelarabine during initial induction or post-remission treatment are eligible only if the physician does not feel they would benefit from other, multi-agent chemotherapy

Patients must not have had chemotherapy or investigational agents within 14 days prior to registration except for corticosteroids, oral 6-mercaptopurine, oral methotrexate, vincristine, intrathecal chemotherapy, or hydroxyurea.

Patients must have no evidence of active >= grade 2 acute graft versus host disease (GVHD) or moderate or severe limited chronic GVHD. Patients must have no history of extensive GVHD of any severity within 90 days prior to registration. Patients who are post-transplant must be off calcineurin inhibitors for at least 21 days to be eligible. Extensive GVHD is defined as 1) generalized skin involvement or 2) localized skin involvement and/or hepatic dysfunction plus liver histology or cirrhosis or involvement of eye or minor salivary organ or oral mucosa or any other target organ

Patients must be >= 12 years of age

Patients ≥ 16 years of age must have a Zubrod Performance Status of 0-3. Patients < 16 years of age must have a Lansky score of ≥ 50

Patients must not have systemic fungal, bacterial, viral or other infection that is not controlled (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement, despite appropriate antibiotics or other treatment) within 14 days prior to registration

Patients ≥ 18 years of age must have creatinine clearance > 30 mL/min within 14 days prior to registration according to the Cockcroft Gault equation

Patients 12-17 years of age must have adequate renal function within 14 days prior to registration defined as serum creatinine ≤ 1.5 x institutional upper limit of normal (ULN) according to age or a calculated estimated glomerular filtration rate (eGFR) (based on Schwartz formula) or radioisotope glomerular filtration rate (GFR) ≥ 50ml/min/1.73 m^2

Patients must have direct bilirubin =< 1.5 x institutional upper limit of normal (ULN) within 14 days prior to registration

Patients must have alanine aminotransferase (ALT) =< 3.0 x institutional upper limit of normal (ULN) or =< 5.0 x ULN (if thought to be related to leukemic involvement) within 14 days prior to registration

Prothrombin time (PT)/partial thromboplastin time (PTT)/ fibrinogen (as clinically indicated for example but not limited to history of bleeding or active bleeding, concern for disseminated intravascular coagulation) (within 14 days prior to registration to obtain baseline measurements)

From metabolic panel (comprehensive or basic): sodium, potassium, chloride, carbon dioxide (CO2), and blood urea nitrogen (BUN) (within 14 days prior to registration to obtain baseline measurements)

Patients must be able to safely discontinue use of strong inhibitors/inducers of CYP3A4 or PgP-g-p and must be able to safely discontinue use of naproxen for 48 hours before and after each dose of OBI-3424

Patients with known human immunodeficiency virus (HIV)-infection are eligible providing they are on effective anti-retroviral therapy and have undetectable viral load at their most recent viral load test within 6 months prior to registration. (HIV viral load testing is required only for patients with known HIV infection). Patients must not be receiving antiviral therapies that are known strong inhibitors or inducers of CYP3A4

Patients with evidence of chronic hepatitis B virus (HBV) infection may be eligible provided that they have an undetectable HBV viral load within 28 days prior to registration. Patients may be currently receiving HBV treatment. (HBV viral load testing is required only for patients with known HBV infection). Patients must not be receiving antiviral therapies that are known strong inhibitors or inducers of CYP3A4

Patients with known history of hepatitis C virus (HCV) infection may be eligible provided that they have an undetectable HCV viral load within in 28 days prior to registration. Patients may be currently receiving treatment. (HCV viral load testing is required only for patients with known HCV infection). Patients must not be receiving antiviral therapies that are known strong inhibitors or inducers of CYP3A4

Patients must not have a known history of prolonged QT interval by Fridericia (QTcF) (interval > 450 msec for males; > 470 msec for females). Patients that had transient prolongation of QTc secondary to medications or electrolyte abnormalities are not excluded if the QTc normalized and remain within acceptable QTcF range (interval > 450 msec for males; > 470 msec for females). Additionally, suspected medications should be no longer required or used, and electrolyte abnormalities must have normalized

Patients must not be pregnant or nursing due to the teratogenic potential of the drug used on this study. Females of reproductive potential must have a negative serum pregnancy test within 14 days prior to registration. Women/men of reproductive potential must have agreed to use an effective contraceptive method during and up to 6 months after treatment. A woman is considered to be of "reproductive potential" if she has had menses at any time in the preceding 12 consecutive months. In addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation. However, if at any point a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures

Patients must not have other active malignancies for which they have received treatments within 6 months prior to registration excluding localized malignancies that do not require systemic treatment
